segmented (version 1.6-0)

Regression Models with Break-Points / Change-Points (with Possibly Random Effects) Estimation

Description

Given a regression model, segmented `updates' it by adding one or more segmented (i.e., piece-wise linear) relationships. Several variables with multiple breakpoints are allowed. The estimation method is discussed in Muggeo (2003, ) and illustrated in Muggeo (2008, ). An approach for hypothesis testing is presented in Muggeo (2016, ), and interval estimation for the breakpoint is discussed in Muggeo (2017, ). Segmented mixed models, i.e. random effects in the change point, are discussed in in Muggeo (2014, ).
